The 1234 problem tests your understanding of the BEDMAS rule.

You must use the numbers 1, 2, 3 and 4, exactly once each, to make the target number. You can also use mathematical operators and symbols, such as brackets and root signs, without limit.

The first target number is 1. The next one is 2. Then 3. And so on!
